Collaboration


Redliner
Although specifically targeted at the business community, Redliner is a site designed for the collaboration and editing of Microsoft Word documents. It takes editing and revision to a new level where individuals can see the changes each member makes and allows users to send messages to one another as they revise. Currently, Redliner is still in its trial phase and it is free to all who want to use it. The website says that in the future, it will operate on a monthly fee.

PB Works
PB Works offers a collection of collaboration tools, with a site devoted specifically to their use in education. What I like most about PB Works is that it stores an audit of all changes made to a document so you can see who has opened the document, when they viewed it, and what changes they made. This helps to eliminate the concerns some teachers have about using Wikis in the classroom. Some aspects of the site are free (there is a special section just for uses in a library!), but others operate on a subscription basis.

GoogleDocs
GoogleDocs is a free, reliable way to collaborate with other people on both Word and Excel documents. You can track the changes that another individual makes and you can have a group of people editing at the same time. (In the past, I have had a Skype conversation while editing a project so we made group changes.) Because it is a program through Google, there are no new accounts to create or passwords to remember. Although the features may not be as extensive as other programs, it is an easy, free option.
